Maurea granti

In the original description, Powell described the species as follows:

Shell acutely conical, moderately solid, inperforate and subangled at the periphery. Spire one and one-half times height of aperture. Outlines straight. Whorls 104, including typical protoconch. Sculpture fine, consisting of numerous closely spaced beaded spiral cords and interstitial threads, crossed by dense microscopic axial growth striae. Early post-nuclear whorls with three beaded cords, later whorls with six, each interspace having a fine spiral thread, which becomes beaded towards the close of the penultimate whorl. Base with twelve beaded cords, four closely spaced at periphery, the remainder more distant; each with a plain interstitial thread. Periphery angled, but not acutely. Columella oblique, arcuate, rather massive. The holotype of the species has a height of 34.25 mm (1.348 in), a diameter of 28.5 mm (1.12 in), and a thickness of 2.90 mm (0.114 in), and a spire angle of 62°. The species has a maximum height of 45 mm (1.8 in) and diameter of 42 mm (1.7 in). The species is polymorphic, differing in shell size, shape and number of spiral cords on the final two whorls. …

The species is endemic to New Zealand, found offshore the North Island south of East Cape and Cape Egmont, South Island, Stewart Island, Auckland Islands, Campbell Islands and Chatham Islands at a depth ranging between 0–360 m (0–1,181 ft). Fossils of the species date back to the Waipipian stage of the Pliocene (3.7 million years ago) in New Zealand.

M. granti primarily feeds on Cnidaria. It is a known host for the slipper snail species Maoricrypta youngi.
